Specification forming part of Letters Patent No'. 174,365, dated March 7, 187; application ijled January 3,1876.

To all whom it may concern l Be it known that I, J AMES L. J AcKsoN, of the city, county, and State of New York, have invented certain new and useful Improvements in the Manufacture of Soap and other Substances in Molds; and I do hereby declare 'that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, which forms part of this specification.

This invention more particularly relates to `the manufacture of transparent and other soap,

which is run, while in a duid state, into molds. These molds are usually of a globular construction, for producing the soap in balls.

The invention, in this relation, has for one of its objects the manufacture of such articles in large numbers, by a single running or filling from the kettle or furnace in which the Saponathe gate. d

The invention likewise includes a peculiarlyconstructed cutting-frame for simultaneously separating the 4connected molded balls or articles in each group or half-box.

Figure 1 is aside view of a series of molds or mold-boxes constructed in accordance with my invention, and Figs. 2 and 3 vertical sections of the same on the lines w .c and y y, respectively. Fig. 4. is a face view of a cuttingframe used in separating' the molded articles or balls of soap, and Fig. 5 a transverse section of the same.

A Al represent a series of vertically-divided mold-boxes. Each of these mold-boxes contain a group of molds, b b, cast with orv constructed in halves in common with the boxes to which they belong, and of which they form a part. The half-boxes A A are made to reg'- ister,so as to bring the halves of each Amold b b together. Each group of molds-that is, the molds in each boX--is provided with, and connected by, upright appel-tures c c, to provide for the filling of the molds froln beneath and expulsion of the air from above. Any number of -these mold boxes are arranged back to back, one against the other, and bolted together by means of cross-bolts d d passing through the molds andL through side plates C C. There are also air-circulating apertures ee between the several mold-boxes,

`through which cooling currents of air are passed to cool the molds after the filling of Athem with soap.

Prior to lling-tlle molds, the several moldboxes thus bolted or clamped together, as described, may be placed on a truck for the conveyance of them to and from the filling kettle or furnace, and a fan or other blower may y be mounted on the truck, for forcing a current or currents of cooling-air, when the truck is in motion, through the air-passages between the molds.

The molds in the several mold-boxes are filled by introducing the melted or fluid soap under hydrostatic or other pressure by a lower filling-tube, D, into a `base-gate, S, constructed to communicate with the lower series of molds b b, through their bottom necks or apertures c c, said gate being composed of longitudinal and transverse passages, so as to connect with all the lower molde throughout the several boxes.

The filling-tube D should be provided- With a cock for opening or closing its communication with the filling kettle or furnace, to control the filling of the molds, and to shut oif the direct supply from the kettle after the molds are filled. Each upper series of molds is filled from the series immediately beneath it, by or through the connecting apertures or necks c c, the soap rising throughout the several molds and forcing out the contained air through the upper necks or apertures c o. This in a measure provides for the soap-balls being made free from honey-comb or being air-blown but tov provide for the shrinkage of the balls in the molds, and to give them increased solidity, Imount on the tube D, between its cock and the several mold-boxes, an upright tube, E, into which the melted soap is forced from below, at the same time that the several molds arel filled,randwhich may either beexte'nded sulciently above the mold-boxes, to give an adequate hydrostatic pressure, or have tted within it a weighted plunger, g, or piston which may be loaded with weights, so that after the molds have been filled,asdescribed,`I` they will be kept charged under pressure by the soap in the tube E. To prevent, however, such'f pressure from torci bly expelling the`4 soap through the apertures c c in the upper series of molds, said apertures should be closed bya frame or `gratin g placed'on the tops 'offthesevi eral molds, and constructed to close suchl ap-fertures, but leaving the air-passages up between the mold-boxes open, to expedite the cooling ot the molds and settling ot'f theV thor' oughlyfcompacted balls vot' soap-in thefmolds. After the soap has been thusmoldedand compacted, the several mold-boxes are'run'o' orreuuovedv from the furnace, the bolts-dd rc1. moved, and thel mold boxes separated onel on or over each half mold-box, in succession,

leontainingjthe balls ot`soap,and so that the cutters l,`whieh, together with' the blades k, are suitably spaced for the purpose, are brought down upon the thin necks ot' soap in the counecting-apertures o ot' the molds. This separates the-.several bal-ls of soap in each group ot' molds, and leaves little or nothing to be ,doneafterward in the way of trimming the balls,"b'yreason''of the molds being integral parts of the boxes, and the thin lms of soapy in the connecting-apertures c c being little or nothic'lrer'than the: thin cutters l which divide'the balls.

I claim- 1. The combination of the vertically-divided mold-boxes A A', theirlo'werdistributinggate"S,=the upright throughy and connecting apertures c 0,1the"moldsfb-byair-passages" e e th rough; the 'moldfboxes, and the independent 'pressure-tube Ef,v .connected withvthe gate S,

essentially asv described.

22 The cutting-trame G, wi'tlieits cutters l l, inlzcombination'wh either half mold-box A or A', col'istructedflto lform molds b-b, having through or connecting 'apertures-'cfa substantially 'as andv for the=purposelherein set forth.
